The first amazing accurate 3D map of the Milky Way has been unveiled by the European Space Agency which could help shed fresh light on the Galaxy.
The Milky Way is the galaxy that contains our Solar System. The name describes the galaxy's appearance from Earth: a band of light seen in the mysterious night sky formed from stars that cannot be individually distinguished without zooming in.
The structure of the Milky Way is thought to be similar to this galaxy: UGC 12158.
The Milky Way is really the second-largest galaxy in the Local Group (after the Andromeda Galaxy).
